Frank McQuillan commented on MADLIB-1410: ----------------------------------------- Thank you [~leskin-in] for opening the PRs. [~okislal] has offered to review them, was just chatting with him now on it. > MADlib cannot be built on PowerPC machines with Linux > ----------------------------------------------------- > > Key: MADLIB-1410 > URL: https://issues.apache.org/jira/browse/MADLIB-1410 > Project: Apache MADlib > Issue Type: Bug > Components: Build System > Reporter: Ivan Leskin > Priority: Major > Fix For: v1.16, v1.17 > > > The most recent version of MADlib cannot be built on PowerPC machines with > Linux (CentOS 7) without extra modifications of the build system. > I have encountered the following problems: > h4. Architecture-specific G++ option is set (on all architectures) > The [current CMakeLists.txt sets the > `-mno-sse2`|https://github.com/apache/madlib/blob/fc81374d4d280ab4454150cb126137775e0f7ae6/CMakeLists.txt#L101] > GNU C++ compiler option, which [is > architecture-specific|https://gcc.gnu.org/onlinedocs/gcc-4.8.5/gcc/i386-and-x86-64-Options.html] > and thus not available on PowerPC machines that use GCC to build MADlib. > For this reason, compilation fails, unless this flag is removed from the > CMakeLists.txt manually. > h4. `architecture` cmake macros works incorrectly > The [current cmake `architecture` > macros|https://github.com/apache/madlib/blob/fc81374d4d280ab4454150cb126137775e0f7ae6/cmake/Utils.cmake#L83] > does not work on PowerPC machines with Linux. Its result is empty string. > As a result, M4 variable `<DBMS>_ARCHITECTURE` is not set properly, and the > installation fails. > > As far as I understand, there are no fundamental limitations on usage of > MADlib on PowerPC machines with Linux. After some manual actions to resolve > the problems _mentioned above_, I have successfully built and installed > MADlib. A simple check with an example from the quick-start guide showed the > correct results. > I would propose to fix the problems mentioned in order for MADlib to support > PowerPC with Linux properly. -- This message was sent by Atlassian Jira (v8.3.4#803005)
